Today I attempted to replace my compressor clutch on my 08 G35 but ran into roadblock. I thought my belt tensioner is the screw type but it turns out to be the type where you need a breaker bar. I was able to borrow a breaker bar, but there doesn't seem to have enough space between the radiator fan cooling assembly and the belt tensioner square hole for the breaker bar to fit. Afterwards, I went to Sears to get a breaker bar with rotating end but I still do not have enough clearance. Does anyone have a DIY for a 2007+ G35 compressor clutch replacement or a DIY for replacing the radiator fan assembly? Thanks.

Try the link above. It is the service manuals for the '07. Should be the same procedure for the '08.

 

Depends, if it's a coupe then it's a VQ37VHR motor, if it's a sedan then it's a VQ35HR motor.
